Received the dehumidifier within 5 days, I'm very happy to have it. The unit works well, is very quiet, and really keeps our basement humidity down. We started at like 79% humidity, and we are now at about 50%. It’s nice and compact. Doesn’t take up much room. Definitely worth the money so far! GREAT EXPERIENCE HIGHLY RECOMMEND THIS SELLER.

This product deserves the title of Energy Star. This dehumidifier will quickly remove moisture from the air without running up my utility bill. In addition, the machine is compatible with Remote Control. Therefore, it is really convenient for me to control.

We live in a high humidity state and had our basement in a desired relative humidity percentage in a short time. The unit automatically shuts down in the reservoir is full and it is very simple to convert and use with a drain as well. The unit is sleek in design and quieter than I expected.

The air was immediately dehumidified on the first day of arrival. My basement smelled much better after a few days! The machine itself is not as loud as other dehumidifiers I have heard, but it does make some noise. It is easy to operate, it has only a few buttons, I only set it once, and it has been running for me for several weeks without any adjustments. So far, so good! This is a high-quality product and definitely worth the money.

So far, so good. It works normally, runs quietly and drains well. It keeps our basement dry and we are happy to find this product because there are not many sophisticated dehumidifiers on the market today. If you need a good dehumidifier, this is a good choice! I would recommend this brand and model!

The product is very good and works as expected. This dehumidifier can definitely take away the moisture in the air in the basement. Once it reaches the humidity level I selected, it will shut down and continue to work when the humidity changes. It is compact, quiet and easy to set up. If you need a dehumidifier, it is definitely worth it.
I highly recommend this product!

We recently purchased it and it has been working well so far. It is very easy to install, especially with a drain hose. We are worried that it may be too small for our basement, but it has reduced the humidity in our basement, and we can feel the obvious difference.
Amazing dehumidifier!

This is really an amazing dehumidifier, it works very well, it is very quiet, the device is not too bulky and easy to use. We use it in the basement to control the humidity there and connect the supplied hose for automatic drainage. It has been in existence for several months and can maintain humidity at around 50% without problems. I highly recommend this product.
Satisfied with our purchase
By 'Charlize Morton ', Reviewed on 2021-02-01 13:43:32
This is an effective dehumidifier, suitable for our basements above 2000 square feet. We have been using it for more than two months, essentially plugging it in and forgetting it. It has reduced the humidity to a comfortable level, which greatly reduces the musty smell. The noise level is so small that we don't pay much attention. If needed, I will buy it again.

No, it's not necessary.
Answered by Alorair
Our units can NOT withstand flooding in the crawlspace. You will need to place it on a dry surface.
Answered by Alorair
The unit comes with a pump, and it will only extract water when the pump reservoir is full.
Answered by Alorair
It is not safe to use the handle to hang it. The handle is used to carry the unit around but not for hanging. You can use a hanging kit that will support the unit from below.

It will give you an option to dehumidify a different room from where the dehumidifier is.
Answered by Alorair
It can control the unit separately, connect the remote control to another room you want to monitor, and be available in our store.
Answered by Alorair
The evaporator drains moisture into the pump, which drains moisture out of the unit. The pump helps to lift the water up to 5 meters if you are draining upwards.
Answered by Alorair
The unit will still work without the controller.
